Technical Field

The invention relates to a tolerance-compensating fastening device for fastening a first vehicle component to a second vehicle component by means of a bolt, a fastening system comprising a fastening device according to the invention, and a method for fastening a first vehicle component to a second vehicle component by means of a bolt.

Background and summary of the invention

The object of the present invention is to improve the disadvantages of tolerance compensating fastening devices.

This object is achieved by the independent claims and individual aspects or the whole combination of the technical content described herein or shown in the drawings. Advantageous further developments are defined in the dependent claims.

This object is achieved in particular by a tolerance-compensating fastening device for fastening a first vehicle component to a second vehicle component by means of a bolt, the fastening device having a longitudinal opening for receiving the bolt, the fastening device having a first compensating unit

-the first compensation unit is arranged to compensate for tolerances in the longitudinal direction (y) within a first tolerance compensation range,

and the first compensation unit has for this purpose a first part to which the movement of the bolt is transferable, preferably by means of one or more friction elements or friction structures of the first or second part, due to friction between the one or more friction elements or friction structures and the bolt,

-and

a) the first part being mounted on the second part of the fastening device, or

b) By mounting the first component on the first vehicle component, the fastening device is preassembled on the first vehicle component via the first component, preferably as a result of which the first axial end of the fastening device faces or is assigned to the first vehicle component,

due to the mounting within this first tolerance compensation range, for example as a result of a displacement or, when there is a threaded mounting (preferably also) as a result of a rotation, the first component is movable in the longitudinal direction (y) in the corresponding mounted state, preferably as long as the end fixing has not yet been achieved by means of the bolt, and thus has a longitudinal degree of freedom,

the fastening device has a second compensation unit

-the second compensation unit is arranged to compensate for tolerances along one or more lateral directions (x, z),

and the second compensation unit has for this purpose one or more connecting and/or guiding elements by means of which,

in case a), the second component or the first component can be preassembled on the first vehicle component, with the result that the second component or the first component can be moved in the direction of the one or more transverse directions (x, z) within a second tolerance compensation range, with the result that the first axial end of the fastening device faces the first vehicle component, or,

in case b) the second part of the fastening device is mounted on the first part or on the other part of the fastening device, as a result of which the second part can be moved in the direction of the transverse direction or directions (x, z) within a second tolerance compensation range,

thus, the second part has one or more lateral degrees of freedom.

As a result, tolerances of the vehicle components can be compensated not only in the longitudinal direction but also in one or more transverse directions. The maximum tolerance compensation range in the transverse direction is preferably the diameter of the shank section which is in the opening in the fastened state of the fastening device.

In a further exemplary embodiment of the invention, the diameter of the fastening device tapers towards a second axial end of the fastening device, which second axial end is located opposite the first axial end and which starts from a shank section, which shank section is located in the opening of the second vehicle component in the fastened state of the fastening device, the reduction in diameter from the shank section to the first axial end being greater than or equal to the second tolerance compensation range.

In another exemplary embodiment of the invention, the one or more connecting and/or guiding elements have an elastic configuration at least in regions, and the second component is arranged in the rest position substantially centrally with respect to the longitudinal axis. As a result, a preferably centered rest position of the device is achieved. By elastically bending the connecting and/or guiding elements, they are left behind, which can be used to compensate for tolerances in the transverse direction, as long as they are required.

In a further exemplary embodiment of the present invention, the one or more connecting and/or guiding elements are configured as flexible hose-like hollow bodies with a circular or angular cross section. As a result, they can be produced in a space-saving and simple manner.

In another exemplary embodiment of the invention, the one or more connecting and/or guiding elements may be compressed in the longitudinal direction. Thus, they can also be pre-assembled fixedly on the device in the pre-installation position as well as in the longitudinal direction, whereby the assembly in the re-installation position is stronger and does not swing around it, in particular in the preferred case when the device is installed, a pretensioning is applied to the connecting and/or guiding element(s) in the longitudinal direction by the bolt, as a result of which the connecting and/or guiding element(s) is/are pressed forward.

In a further exemplary embodiment of the invention, the one or more connecting and/or guiding elements are at least partially, preferably completely, formed of foam. As a result, cost-effective production can be achieved.

In another exemplary embodiment of the invention, the one or more connecting and/or guiding elements are at least partially, preferably completely, formed by a serpentine shaped circumferential surface, preferably formed by a plastic material. As a result, alternative cost-effective production may be performed.

In another exemplary embodiment of the invention, the one or more connecting and/or guiding elements are at least partially configured as helical springs, preferably with two or more spring stops. As a result, these can alternatively be produced in a space-saving and simple manner

In another exemplary embodiment of the invention, the one or more connecting and/or guiding elements are at least partially configured as a latching retainer. Thus, a quick pre-assembly of the fastening device is provided, which also already at least partly remains together without bolts.

In a further exemplary embodiment of the invention, the first vehicle component and/or the second component have one or more corresponding holders for holding the one or more connecting and/or guiding elements in a positively locking manner, preferably at least with respect to the one or more transverse directions.

In a further exemplary embodiment of the invention, the fastening device is provided to fix the longitudinal degree of freedom of the first component and/or one or more transverse degrees of freedom of the second component in a friction-locked and/or positive-locked manner by means of a pressure force acting on the first and/or second component by means of the bolt. As a result, the adjusted compensation is fixed specifically, and the result of fastening the bolt is obtained.

In a further exemplary embodiment of the invention, the fastening device has one or more ribs or prongs which are arranged to fix the longitudinal degree of freedom and/or one or more transverse degrees of freedom in a friction-locked and/or positive-locked manner. As a result, an advantageous and simply producible fastening is provided.

In another exemplary embodiment of the present invention, the first member is rotatably movably mounted by a first thread,

in case a), the fastening device is provided on a second part of the fastening device, in a second thread of the second part, or,

in case b), on the first vehicle component, in the second thread of the vehicle component, the movement of the bolt that can be transmitted to the first component is a rotation of the bolt.

The first and second threads are preferably concentric with one another. They are preferably also concentric with the longitudinal opening. The direction of rotation of the first and second thread is preferably opposite to the direction of rotation of the bolt to be used, particularly preferably the same. The first and second threads are preferably left-hand threads, particularly preferably right-hand threads. In a particularly preferred manner, the threads are not self-locking with respect to one another, as a result of which it is possible to dispense with friction elements, since the necessary entrainment of the first part and thus the transmission of the bolt movement, which is preferably effected precisely by the bolt head, is possible.

In another exemplary embodiment of the invention, the first component is mounted such that the first component is displaceable along the longitudinal degree of freedom by means of a thrust joint,

in case a), on the second part of the fastening device,

in case b), on the first vehicle component,

the movement of the bolt that can be transmitted to the first component is a displacement of the bolt. As a result, the necessary entrainment of the friction element as the first component can be dispensed with, so that the transmission of the bolt movement can be achieved, preferably precisely by means of the bolt head.

In another exemplary embodiment of the invention, the fastening device has one or more expansion structures which are arranged to be expanded by means of pressure acting on the first and/or second component by means of the bolt, thereby blocking the longitudinal freedom of the thrust joint.

In another exemplary embodiment of the invention, the fastening device has a nut element for fastening the fastening device to the opening of the second vehicle component, which nut element is arranged at a second axial end located opposite the first axial end and is arranged to be radially expanded by means of a bolt screwed into the fastening device. As a result, it is possible to install particularly quickly from only one side of the second vehicle component.

In another exemplary embodiment of the invention, the fastening device has a nut element for fastening the fastening device to the second vehicle component, which nut element is arranged at a second axial end located opposite the first axial end and is arranged to be rotated by a bolt screwed into the fastening device from an introduction position into a locking position, which locking position is defined by a stop. As a result, it is possible to install particularly quickly from only one side of the second vehicle component.

In another exemplary embodiment of the invention, the nut element has an elongated cross section, as a result of which the nut element can be introduced into a correspondingly elongated-shaped opening of the second vehicle component and thus be arranged to undercut said opening transversely and thus lock it in the blocking position, preferably rotated by 90 ° relative to the introduction position. Thus, a larger undercut and thus a stronger fastening can be achieved than in the case of, for example, a secondary cross-section and a 45-degree difference between the introduction position and the blocking position.

In a further exemplary embodiment of the invention, the nut element is held in a cage having a preferably polygonal, particularly preferably rectangular, preferably square cross section, the nut element having a radial projection which terminates radially in the cross section or has the same radial dimension as the cross section in the introduction position and projects radially beyond the cross section in the locking position. As a result, the nut portion can be preassembled in the device even without the bolt.

In a further exemplary embodiment of the invention, the cage or the further component (preferably the second component) of the fastening device has one or more preferably helical guide bends, preferably as an edge of one or more nuts or recesses introduced into the cage, for axial and/or rotational guiding of the nut element, preferably one or more radial projections.

As a result, the nut element is guided in rotation by the force of the bolt, which results in the nut element being reliably in the locked position when the bolt is screwed in. Furthermore, when there are axially two sides of the radial projection, i.e. a helical guide (for example in the case of a groove), disassembly becomes easier as the bolt can initially be unscrewed slightly, and then, due to the pressure exerted on the bolt, the nut element can be reliably moved back again into the introduction position. For this purpose, the holder preferably has a stop defining the introduction position.

The object is also achieved in particular by a tolerance-compensating fastening device for fastening a first vehicle component to a second vehicle component by means of a bolt, the fastening device having a longitudinal opening for receiving the bolt, the fastening device having a first compensating unit

-the first compensation unit is arranged to compensate for tolerances in the longitudinal direction (y) within a first tolerance compensation range,

and the first compensation unit has for this purpose a first part to which the movement of the bolt can preferably be transmitted, due to friction between one or more friction elements or friction structures and the bolt, preferably by means of one or more friction elements or friction structures of the first or second part,

-and

a) the first part being mounted on the second part of the fastening device, or

b) By mounting the first component on the first vehicle component, the fastening device is preassembled on the first vehicle component via the first component, preferably as a result of which the first axial end of the fastening device faces or is assigned to the first vehicle component,

due to the mounting within this first tolerance compensation range, for example as a result of a displacement or, if there is a threaded mounting (also preferably), as a result of a rotation, the first component is movable in the longitudinal direction (y) in the corresponding mounted state, preferably as long as the end fixing has not yet been achieved by means of the bolt, thus having a longitudinal degree of freedom,

the fastening device has a nut element for fastening the fastening device to the opening of the second vehicle component, which nut element is arranged at a second axial end located opposite the first axial end and is arranged to be radially expanded by means of a bolt screwed into the fastening device or to be rotated from an introduction position to a locking position defined by a stop by means of a bolt screwed into the fastening device. As a result, it is possible to install particularly quickly from only one side of the second vehicle component.

The fastening device preferably also has individual or each of the features of the fastening device described previously.

The object is also achieved in particular by a tolerance-compensating fastening device for fastening a first vehicle component to a second vehicle component by means of a bolt, the fastening device having a longitudinal opening for receiving the bolt, the fastening device having a first compensating unit

-the first compensation unit is arranged to compensate for tolerances in the longitudinal direction (y) within a first tolerance compensation range,

and the first compensation unit has for this purpose a first part, the movement of which bolt can preferably be transmitted to the first part of the first compensation unit, preferably by means of one or more friction elements or friction structures of the first or second part, due to the friction between the one or more friction elements or friction structures and the bolt

-and

a) the first part being mounted on the second part of the fastening device, or

b) By mounting the first component on the first vehicle component, the fastening device is preassembled on the first vehicle component via the first component, preferably as a result of which the first axial end of the fastening device faces or is assigned to the first vehicle component,

due to the mounting within the first tolerance compensation range, for example as a result of a displacement or, if there is a threaded mounting (also preferably), as a result of a rotation, preferably as long as the end fixing has not yet been achieved by means of the bolt, the first component is movable in the longitudinal direction (y) in the corresponding mounted state and thus has a longitudinal degree of freedom,

the first part is mounted in a rotationally movable manner by means of a first thread,

in case a), the fastening device is provided on a second part of the fastening device, in a second thread of the second part, or,

in case b), the thread profile is determined on the first vehicle component, in the second thread of the vehicle component,

the first thread and the second thread are configured such that they do not create a self-locking effect and thus form a push joint or a push-turn joint along a longitudinal degree of freedom,

and the movement of the bolt that can be transmitted to the first component is a rotation of the bolt and/or a displacement of the bolt in the longitudinal direction. As a result, a simpler, faster and more accurate compensation in the longitudinal direction can be achieved. The friction element can (and preferably also) be dispensed with, since the first part is axially movable for compensating tolerances in the longitudinal direction, also due to the pushing of the bolt. As a result of the tightening of the bolt, the rotational position of the first component is fixed relative to the second vehicle component. As a result, when the first vehicle component is still advantageously connected to the second vehicle component via a point, then the tolerance compensation is fixedly set in the longitudinal direction also taking into account the thread (as opposed to a pure slip joint as in fig. 3a, 3b, for example), with the result that rotation about the axis defined by the bolt is no longer possible between two further vehicle components. The connection to another point is preferably effected by a second such tolerance compensating fastening means.

The fastening device preferably also has individual or each of the features of the fastening device described previously.

Two suitable threads are preferably self-locking when the bolt cannot move in an axial rotational manner due to axial pressure on the threaded part (e.g. bolt). Two suitable threads are preferably not self-locking when the bolt is able to move in an axially rotational manner due to axial pressure on the threaded part (e.g. bolt).
